Roto AL Designo is the elegant completely concealed hardware for large and heavy aluminium windows up to 150 kg. It meets the most stringent demands of planners and architects with regard to perfect appearance, functionality and ease of fabrication.
Our top model in the aluminium sector is of a modular design based on the proven Roto design principle and can be integrated into almost all Euro-chamber profile systems.
When everyday requirements are no longer enough, Roto Object Business is your reliable partner for the safe and efficient implementation of your projects.
We provide customised special solutions for high-quality aluminium windows and doors that cannot be implemented without further processing when using standard hardware systems.
The new Roto Designo AL hinge side for window sashes up to 180 kg is an evolution of the proven hardware solution for sash weights up to 150 kg.
The maximum sash height of 3,000 mm enables generously sized room-high window elements to be realized in keeping with the current fashion.
The new hinge side is offered as alternative when sash weights or dimensions exceed the allowable application diagrams of the 150 kg hinge side. Thus depending on the target group, sales opportunities, design competence and the property’s attractiveness increase as a result.
